You noticed a small crack in your windshield. Should you wait or fix it right away? Even a tiny crack can spread faster than you think, especially in Ontario’s changing weather. Acting quickly could save you the cost of full replacement.
At Dixie Auto Glass, we have seen countless chips turn into large cracks in a matter of days. This guide explains what causes cracks to spread and how to prevent costly damage.
Why It Matters
According to Transport Canada, a damaged windshield weakens the vehicle’s crash protection and can fail during a collision. GlassBYTEs also warns that untreated chips often grow rapidly because of vibrations and temperature swings.
Delaying repair increases your safety risk and can lead to higher costs.
How Fast Can a Crack Spread?
Several factors affect how quickly a crack grows:
- Temperature Changes: Hot and cold cycles can expand cracks within hours.
- Road Vibration: Driving over bumps and potholes accelerates spreading.
- Moisture: Water seeping into the crack weakens the glass bond.
- Pressure: Slamming doors or heavy snow on the windshield increases stress.
On average, a small chip can spread across your windshield in a few days to a few weeks if left untreated. If you’re unsure whether repair or replacement is needed, our windshield repair and replacement service can guide you.
What Happens if You Wait?
- Higher Costs: A simple repair may turn into a full replacement.
- Failed Safety Inspection: Your vehicle may not pass certification.
- Legal Issues: Driving with impaired visibility can result in fines.
- Reduced Protection: The windshield is more likely to shatter in an accident.
